Question / Problem

How do I program pulse operation (a short timed ON event) on the ET70000 Series timer?

Common Application / Operating Conditions

Pulse operation is used when the load requires only a brief ON period rather than a sustained ON time. Typical applications include bells, buzzers, momentary triggers, and signaling devices. Each pulse must be assigned to a specific time or Astronomic event.

Step-by-Step Resolution

  1. Start in RUN

    Move the RUN/SET switch to RUN before selecting circuits.

  2. Select Circuits to Program

    Enable only the circuits that will use pulse operation. Disable all other circuits.

  3. Enter SET Mode

    Move the RUN/SET switch to SET to begin programming.

  4. Open the Programming Menu

    Press PROG to begin entering events.

  5. Select the Day or Days

    Press ALL/0 to apply the pulse to all days, or press a specific day key (SUN/1 through SAT/7) to program a single day.

  6. Confirm the Selected Day

    Press OK to confirm.

  7. Enter the Pulse Start Time

    Select how the pulse will start:

    • For a set time, enter the time and press AM or PM.
    • For Astronomic activation, press ASTRO until SUNRISE or SUNSET appears.

  8. Select Pulse Operation

    Press PULSE to change the event from a standard ON event to a pulse event.

  9. Enter the Pulse Duration

    Enter the number of seconds the output should remain ON (e.g., 5 for a five-second pulse).

  10. Confirm the Pulse Event

    Press OK to save the pulse event.

  11. Add Additional Pulse Events (If Needed)

    Repeat the above steps for additional pulse events with different start times or durations.

  12. Save the Programming

    Move the RUN/SET switch back to RUN to activate the programmed pulse events.

Tips / Additional Notes

  • Pulse operation turns the circuit ON only for the programmed duration, then automatically turns it OFF.
  • Each pulse event can have its own start time and duration.
  • Pulse events can be paired with Astronomic activation when momentary ON periods are needed at sunrise or sunset.
